WELLS UMBERGER BRIGGS AND HARRY MORRIS MICHAEL, OF ALAMOSA, COLORADO.

LAWN-SPRINKLER.

Application filed July 27, 1914-.

To all whom it may concern:

Be it known that we, WELLS UMBERGER Ramos and HARRY MORRIS MIGHAEL, citizens of the United States of America, residing at Alamosa, in the county of Alamosa and State of Colorado, have invented certain new and useful Improvements in Lawn- Sprinklers, or which the following is a specification.

This invention relates to lawn sprinklers, of that type designed for rotation by the action of the water as it passes through the discharge openings or nozzles in the sprinkler head, and one of the principal objects of the invention is to simplify the construction of the top or dome of the sprinkler by providing a nozzle formed with discharge openings which will rotate the discharge nozzle and throw the water outwardly from the sprinkler.

Another object of the invention is to provide a cap or dome for a lawn sprinkler, preferably made of sheet metal, and provided with a series of openings stamped up from the sheet metal which will rotate the sprinkler head by the pressure of water projected against it and out through the openmgs.

Still another object of the invention is to provide a discharge opening for a lawn sprinkler formed in a dome or disk to be connected to the sprinkler head and provided with semi-funnel-shaped discharge elements arranged in series around the dome or disk, the openings being formed in the larger portions of the semi-funnel-shaped elements.

These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which Figure l is a side elevation of a lawn sprinkler made in accordance with this invention, and showing the hose connection broken away. Fig. 2 is a perspective View of a fragment of the dome or cap, and showing the semi-funnel-shaped discharge openings arranged reversely, for a purpose which will presently appear and Fig. 3 is a similar view of a piece of flat metal with the semi-funnelshaped openings, this being a modified form of the sprinkler head which may be utilized if desired.

Referring to the drawings the numeral 1 Specification of Letters Patent.

Serial No. 853,387.

designates-a support for a sprinkler head, said support comprising two spaced supporting members having an integral elbow 2 connected therewith and provided with a threaded bore for the connection of a hose 3 at one end and threaded at the opposite end for the connection of a sprinkler head. This sprinkler head comprises the rim 4 to which is connected a central portion 5 mounted on ball bearings 6.

The dome 7 which forms the subject matter of this invention is preferably formed of sheet metal and provided with a series of discharge openings 8 extending around near the lower edge of the dome. The openings 8 are formed in'the sheet metal by making a straight slit 9 in the metal and forcing out the semifunnel-shaped elements 10. The force of water, or the pressure is usually sufficient to rotate the cap or dome too rapidly and in order to overcome this defect it is found necessary to reverse the position of the openings as shown in Figs. 1 and 2, by providing a small number of openings projecting in one direction, and a larger numher in the opposite direction in position to rotate the sprinkler head at the desired speed. The funnel shaped elements 10 in the dome or cap 7 are projected oppositely to the openings or funnel-shaped devices 10. It will be obvious that any suitable number of reversely disposed semi-funnel-shaped elements may be utilized, depending upon the force of the water and the speed at which it is desired to rotate the sprinkler head.

As shown in Fig. 3 the disk 7 a is not dome shaped as shown in Figs. 1 and 2, and good results are attained by this form of sprinkler head. The openings 8, the semi-funnelshaped elements 10 and the slit 9 are formed precisely like those already described, and they serve exactly the same purpose. It will be apparent that the form of openings and semi-funnel-shaped elements may be utilized for many purposes other than lawn sprinklers. For instance a fiat plate like that shown in Fig. 3 provided with the peculiar form of discharge openings could be utilized as one of the elements of a turbine wheel for steam or water, and any suitable number of these elements could be employed to give greater force or speed.

Various changes may be made in details Patented Apr. 13, 1915.
